Resets all iOS, watchOS, and tvOS simulators

resetsims.js

'use strict';

const execSync = require('child_process').execSync;
const json = JSON.parse(execSync('xcrun simctl list --json'));

for (const runtime of Object.keys(json.devices)) {
	for (const device of json.devices[runtime]) {
		console.log(`Removing ${device.name} (${device.udid})`);
		execSync(`xcrun simctl delete ${device.udid}`);
	}
}

for (const deviceType of json.devicetypes) {
	for (const runtime of json.runtimes) {
		if (runtime.isAvailable || runtime.availability === '(available)') {
			console.log(`\nCreating ${deviceType.name} with ${runtime.name}`);
			try {
				execSync(`xcrun simctl create '${deviceType.name} ${runtime.name}' ${deviceType.identifier} ${runtime.identifier}`);
				console.log('SUCCESS!');
			} catch (e) {}
		}
	}
}

console.log();
console.log(execSync('xcrun simctl list').toString());

Its works as per this tidev/ioslib#114 but actual issue not able to solve using this.

As the error indicates, your simulator is not available. You should try to manually launch it, then reset it. You can also do this via simctl.

Secondly, tn is a community project and is not supported by me or the Titanium team, please use the Appc CLI (or Titanium CLI).

Lastly, this gist is not the correct place to get Titanium support. I recommend hopping on https://ti-slack.slack.com/ or request an account at https://jira.appcelerator.org/ and file a ticket.
